hi There,

I'm just trying to write a little sample program with a thread. I can't get my thread started and am not sure why, I get
$ g++ -o example example.cpp
example.cpp: In member function ?int MyThread::StartMe()?:
example.cpp:42:59: error: expected primary-expression before ?void?

void is a type, you can't pass a type as a parameter!

example.cpp:42:63: error: initializer expression list treated as compound expression
the code:
int MyThread::StartMe(void)
{
int pthread_create(&ThreadA, NULL,&MyThread::PrintMsg, void);

This looks like a mixed up function declaration!

int something = pthread_create( );

A decent compiler should tell you that MyThread::PrintMsg is the wrong
function type for the function pointer parameter of pthread_create.

}
//-------------------------------------------------------------

void MyThread::PrintMsg(void)
{
cout<< "I Incremented count: "<< count<< endl;
}

Can anyone point it out? I'm like HUH???

Thanks,
